Answer:

F = 10.2 N

Last option is correct.

Step-by-step explanation:

We can apply Hooke's law to find the force required to stretch the spring.

From Hooke's law, we have

F = k x

Here, F = force required to stretch the spring

k = spring constant

x = length that the spring has been stretched.

We have,

x = 1.2 m

k =8.5

Thus, the force is given by

F = 8.5 × 1.2

F = 10.2 N

Last option is correct.

Ostrovityanka [42]

Answer:

dC/dt = 2 mg*cm³/s

Step-by-step explanation:

Given

C(t)= (1/2)*(4t+ 4)- (1/2)

we apply dC/dt as follows

dC/dt = d((1/2)*(4t+ 4)- (1/2))/dt = (1/2)*(4) = 2

⇒   dC/dt = 2 mg*cm³/s
